QS Concept.
Independent QS advice for construction projects
before important commercial decisions are made.
Fixed-scope advice on cost, scope, contract position, and payment before contracts are signed, budgets are relied on, or payments are approved.
Most cost problems are not caused by pricing — they come from assumptions that were never properly tested.
WHEN CLIENTS BRING US IN
Usually because a contract, budget, variation, or payment needs to be checked properly before the client commits.
A budget or cost plan has been prepared, but the assumptions have not been tested.
The numbers may look acceptable on paper, but key allowances, exclusions, or constraints need an independent review.
A tender looks competitive, but the commercial position is not yet clear.
Pricing, scope gaps, exclusions, or contract terms need to be reviewed before anything is accepted or signed.
A payment, variation, or final account is about to be approved.
Money is about to move, and the entitlement, rates, quantities, or contract position need independent checking first.
The commercial position is no longer clear.
The cost, scope, contract or payment position has become uncertain, and the client needs an independent review before taking the next step.
WHAT WE ACTUALLY DO
QS Concept provides short, fixed-scope reviews of project cost, scope and contract positions.
We test the numbers, examine the supporting information and identify the issues that matter to the client’s decision.
CLARIFY THE POSITION
Establish what is included, excluded, assumed and still uncertain across budgets, scope and likely cost exposure.
REVIEW THE DETAIL
Test tenders, contract terms, claims and payment positions against the supporting information.
SUPPORT THE NEXT STEP
Present the key findings, risks and implications in a clear, practical form.
HOW WE STEP IN
Fixed-scope. Fixed-fee. Brought in when an independent review is needed.
Each Capsule is a defined way to review the commercial position, clarify risk, and support the next decision.
Feasibility Capsule
Early testing of project scope, budget and key assumptions before design or procurement progresses too far.
Used where the client needs to determine whether the project basis is realistic before investing further.
Cost Certainty Capsule
Review of developed budgets, allowances and scope before key numbers are relied on.
Used where the likely cost position needs to be clearer before commitment.
Tender & Contract Review Capsule
Review of pricing, exclusions and contract terms before anything is accepted or signed.
Used where the tender looks workable, but the commercial position needs checking properly.
Payment Assurance Capsule
Review of claims, variations and payment positions before money moves.
Used where entitlement, rates, quantities or supporting records need checking before an amount is agreed or approved.
